Hex String to Character in PURE Swift

Question

I need a way to convert a string that contains a literal string representing a hexadecimal value into a Character corresponding to that particular hexadecimal value.

Answer 1

Another simple way based on ICU transforms:

extension String {
  func transformingFromHex() -> String? {
    return "&#x\(self);".applyingTransform(.toXMLHex, reverse: true)
  }
}

Usage:

"2C".transformingFromHex()

Results in: ,
